Rollway E-5222 Bearing Outer Ring Precision Ball Bearing

Rollway E-5222-B radial cylindrical roller bearing provides high radial stiffness with a separable inner ring and a non-separable outer ring, optimizing installation and maintenance in demanding radial-load applications. This straight-bore unit features a 110 mm bore, 200 mm outside diameter, and 69.9 mm width, with cage-guided rollers and an unsealed design for standard industrial service. It is manufactured from high-carbon chromium bearing steel (52100 family) and finished to RBEC 1 tolerances, delivering precise geometry and consistent radial clearance for reliable shaft guidance. Typical uses include machine tools, material-handling conveyors, and other heavy-duty industrial equipment where robust radial support and serviceable inner components are advantageous. The inner ring is separable from the outer race, enabling straightforward mounting and disassembly without removing the outer race.
